Headphones Not Loud Enough

I'm wondering if it's just my headphones, as I am running cheaper SONY headphones in lieu of having lost the pair of more expensive SONY's I usually use. But I am also on a new Dell Inspiron, so maybe that's a factor. Anyway, the RealTek High Definition Audio Output is all the way up. I still can't hear things well enough to do any kind of halfway decent mix, hardly hear the bass at all, in fact. Isn't there any way to simply increase the volume on the headphones, besides what I've already done? Thanks...
